Halo 4 Specializations: What to do if you have not received your unlock code

XMNR: We've been reporting on the situation with the Halo 4 Specialization unlocks since Microsoft first announced that all eight Specializations would come to those that played the Xbox 360 shooter by Nov. 20. Since the final emails containing the unlock were sent out this past Saturday, we have been inundated with emails and comments from players who say that they meet all the eligibility requirements but have not received their code yet. 343 Industries provided an update Sunday on the status of the issue and what to do if you are one of the unlucky ones.
